Emergency landing grounds Boeing 787 jets in Japan

TOKYO  Japan’s two biggest airlines grounded all their Boeing 787 aircraft for safety checks Wednesday after one was forced to make an emergency landing in the latest blow for the new jet.

All Nippon Airways said a cockpit message showed battery problems and a burning smell was detected in the cockpit and the cabin, forcing the 787 on a domestic flight to land at Takamatsu airport in western Japan.

The 787 is Boeing’s newest and most technologically advanced jet, and the company is counting heavily on its success.

Since its launch, which came after delays of more than three years, the plane has been plagued by a series of problems including a battery fire and fuel leaks. Japan’s ANA and Japan Airlines are major customers for the jet and among the first to fly it.

Japan’s transport ministry said it received notices from ANA, which operates 17 of the jets, and Japan Airlines, which has seven, that all their 787s would not be flying.
